Answers & Solutions:
1) Answer (C)
(15 – 6) * 3 = 27
(19 – 8) * 2 = 22
(23 – 15) * 4 = 32
Hence, option C is the right choice.
2) Answer (C)
8*6 / 3 = 16
15 * 2 / 6 = 5
7 * 18 / ? = 9
? = 14
Hence, option C is the right choice.
3) Answer (A)
(3 + 5) * 3 = 24
(9 + 4) * 2 = 26
(5 + 6) * 4 = 44
Hence, option A is the right choice.
4) Answer (D)
In each column, the middle row is twice the sum of the first and the last row.
64 = 2*(19 + 13)
116 = 2*(37 + 21)
Hence, 2*(53+22) = 150
Option D is the answer.
5) Answer (D)
In each column, the third row is the cube of the difference of the first two rows.
$216 = (117 – 111)^3$
$1331 = (80 -69)^3$
Similarly,
$343 = (106 – 99)^3$
6) Answer (A)
$4^2 – 6^2 + 11^2 = 101$
$7^2 – 9^2 + 12^2 = 112$
$ ?^2 = -8^2 + 5^2 + 139 = 100 = 10^2$
Hence, option A is the right choice.
7) Answer (D)
The sum of three digits in the horizontal row is equal to 30
1) 5 + 15 + 10 = 30
2) 4 + 17 + 9 = 30
3) 10 + x + 10 = 30 ; x = 10
Hence, option D is the correct answer.
8) Answer (B)
The pattern followed is that the number in the last row is obtained by multiplying the other two.
Eg :- $3\times7=21$
$5\times6=30$
Similarly, $8\times1=8$
=> Ans – (B)
9) Answer (B)
The logic followed here is,
$\sqrt{49}$ + $\sqrt{81}$ $\Rightarrow$ 7 + 9 = 16,
$\sqrt{169}$ + $\sqrt{144}$ $\Rightarrow$ 13 + 12 = 25,
$\sqrt{484}$ + $\sqrt{624}$ $\Rightarrow$ 22 + 25 = 47.
Hence, option B is the correct answer.
10) Answer (D)
The pattern followed for $a,b,c$ and $d$ in each column is : $a=(c\times d)-b$
Eg :- $(3\times5)-6=15-6=9$
$(3\times4)-7=12-7=5$
Similarly, $(x\times7)-6=8$
=> $7x=8+6=14$
=> $x=\frac{14}{7}=2$
=> Ans – (D)
11) Answer (B)
The pattern followed is that the alphabets are numbered alphabetically, A=1, B=2, C=3 and so on and then the first alphabet in each column is obtained by :
D=4 and N=14, => $4+14=18\equiv R$
V=22 and B=2, => $22+2=24\equiv X$
Similarly, L=12 and F=6, => $12+6=18\equiv R$
=> Ans – (B)
12) Answer (B)
In each column, the number at the end is the average of other two.
Eg :- $\frac{(36+72)}{2}=\frac{108}{2}=54$
$\frac{(44+88)}{2}=\frac{132}{2}=66$
Similarly, $\frac{(32+64)}{2}=\frac{96}{2}=48$
=> Ans – (B)
13) Answer (B)
The pattern followed is that in each column, the number at the middle is obtained by multiplying the other two.
Eg :- $12\times9=108$
$9\times8=72$
Similarly, $9\times x=36$
=> $x=\frac{36}{9}=4$
=> Ans – (B)
14) Answer (B)
The pattern followed is that in each row, the number at the middle is obtained by multiplying the other two.
Eg :- $6\times7=42$
$8\times4=32$
Similarly, $9\times5=45$
=> Ans – (B)
15) Answer (C)
The sum of each column is same.
Eg :- $6+7+3=16$
and $10+2+4=16$
Similarly, $9+1+x=16$
=> $x=16-10=6$
=> Ans – (C)
